Installation Instructions
RPX/Lite Rear Projection System by Draper
Caution
➀ Inspect your Draper rear projection screen immediately upon delivery.
RPX/Lite units ship in up to three crates which may be bolted together
for shipping. After inspection has been made, the shipping crates should
be sealed until installation.
➁ Before beginning assembly/installation, compare the custom as-built
drawings with the pieces you have, and make sure you have received
the proper Rear Projection System, and that all parts are included.
➂ Make sure RPX/Lite is installed level and square. If unit is not level, or
not square in relationship to the projection screen, "keystoning" or other
problems will be encountered.
➃ All tools and hardware for assembly are included; do not discard.
➄ Installation instructions for your Draper rear projection screen are
shipped with the screen.
➅ Take great care when handling the mirror. Projector Side is delicate and
will usually come covered with a protective plastic film. Remove film after
installation and prior to projecting images. If cleaning is necessary, a mirror cleaning kit is available; contact Draper. You may also clean lightly
with glass cleaner and a soft, lint free cloth.
➆ Assemble all components of the mounting system with nuts and bolts
securely tightened.
These instructions are meant as a guide only. They do not bind Draper,
Inc. in any way and do not imply responsibility of Draper, Inc. for improper
installation or faulty workmanship at the jobsite.
Receiving
All Draper rear projection screens are shipped (with installation instructions) in durable wooden crates and packaged in accordance with accepted
standards for this type of material. However, occasionally a shipment will
incur freight damage due to particularly rough handling in transit. Your Draper
rear projection screen and RPX unit should be inspected immediately
upon delivery. Any obvious damage should be noted on the freight bill when
the shipment is received. If concealed damage is discovered, an inspection
by a representative of the delivering carrier must be made within 14 days
following receipt of shipment. Neither Draper, Inc. nor our dealer can accept responsibility for claims arising from merchandise damaged in shipment unless
the above procedure is followed. After inspection has been made, the shipping
crate should be sealed until installation.
NOTE: Draper rear screens are extremely delicate. All Draper rear projection screens should be handled and stored upright at all times.
screens be installed with the Fresnel lens (circular pattern) facing the projection room and the linear lens (straight pattern) facing the audience. IRUS
screens must be installed with side marked "audience side" facing audience.
Cinescreens® work equally well with the optically coated side facing the projector or the audience. Rear projection screens are most frequently mounted
with the optically coated side toward the audience, as this greatly reduces
glare and reflections from ambient light in the audience area. However, care
must be taken on screens so mounted to protect the coated surface from accidental damage or abuse.
A Draper screen with a factory-installed System 400 frame can only be
mounted in an opening one way: with the frame trim toward the audience. No
finish carpentry work is required with a System 400 frame.
A Draper screen with a factory-installed System 100, 200, or 300 frame
must be mounted within a finished opening. See screen instructions for installation drawings.
Cleanup
If cleaning is necessary, a mirror cleaning kit is available; contact Draper.
Dust may be removed from Draper rear projection screen surfaces with a soft
clean cloth. For removal of stains or soil marks with a cloth or sponge and a
mild soap and distilled water solution. Wring free of excess moisture before
applying, rinse and blot dry. Do not rub. Do not use solvents of any type
without Draper’s recommendation.

Unpacking
All Vortex, Cinescreen, DiamondScreen™, High Contrast Black and IRUS
crates are labelled on the “PROJECTOR SIDE.” Open crates only from the
side marked “OPEN THIS SIDE.” Use extreme care in unpacking to avoid
scratching the lens surfaces. Do not use knives to remove wrapping. Use soft
cotton gloves, a soft cloth or tissue paper as a hand pad.

lens direction and projector placement.
Installation
Make sure all other aspects of construction have been completed before
rear screen installation, including painting and cleanup. If additional construction work must be done after installation, cover screen with clear polyethylene
sheeting until all work has been completed.

Draper screen after it leaves our plant automatically voids product warranty.
